Hi all,
just a very simple question. In the datasheet of TMS320F28377D, I read that the ADC VREFHI can be 2.5V or 3V.
Is VREFHI = 3V for TMS320F28377D?
thank you
Leonardo
Hi Leanardo,
Please go through the below infosheet document for those information.
TMDSCNCD28377D-Infosheet_v1_5.pdf
Based on switch settings, VREFHI will be selected.

Aditya
Hi Leonardo,
I wanted to clarify that what Aditya is describing is true of the controlCARD evaluation kit.
The TMS320F2837*D chip isn't quite so specific. However, an important thing to know is that there is no internal way to source VREFHI. They must be supplied externally. The image you posted above (from the datasheet) provides the range of voltage reference inputs that can be used.
If you wish to use an evaluation kit as a guide for what might be possible, I'd recommend taking a look at the controlCARD schematics within controlSUITE:
\controlSUITE\development_kits\~controlCARDs\TMDSCNCD28379D_v1_0\R1_3\
Thank you,
Brett
Hi leanardo,
switch setting is: SW3 and SW4 all to the right and SW2 all up. VREFHI should be 3.3V in this configuration if I have understood correctly.
Yes. In this case, VEREFHI will be selected as 3.3V.

Aditya
